Bug is still here from version 1.0.x till 1.8.x, why there aren't any improvements for Zend_Feed for about a year?
Another notice, It's maybe duplicate with ZF-5833.

I think there isn't any support for Zend_Feed nowadays :-(

Just surprised it was there since Feb 2008. It was an obvious flaw with an easy fix overall. Unfortunately Zend_Feed is a bit of a mess and it's being superseded by Zend_Feed_Reader, and soon Zend_Feed_Writer.
